This is to give both sides some buffer time and space; otherwise, asking directly would make it awkward. Yurong thought that if Hai Fu and Li Yan truly had something going on, and she knew she was married to Li Yan, she definitely wouldn't invoke the saying "ignorance is no crime". She would feel guilty towards herself, and therefore, leave the company.
She didn't lie; the facts she needed to disclose were both directly (about Li Yan) and indirectly (about them) already conveyed.
Hai Fu was the most difficult one. After making her call, Yurong felt so constrained and tense, she wasn't very familiar with Li Jie and thus straightforwardly called her.
"You finally returned my call! Are you okay?" Li Jie reacted with urgency just like Hai Fu.
And Zhang Yurong also gave the same response: "Li Yan has returned home and is temporarily unavailable to take calls. He didn't have time earlier; now I finally have time to call you back."
